Sometimes planning can take so long that some players get frustrated and just get up and go in and raid the base, guns a-blazing.

When this happens when they are planning what equipment to buy from the friendly local blacksmith or ship-chandler, you know things are taking way too long.

GM: So what are you two doing?
C-3PO: We're going to Jabba's palace, to rescue Han.
GM: What about the others?
Leia: We're on the Falcon, coming up with an actual plan.
Chewbacca: I would like to register that disguising Luke as a Wookiee is an appalling idea.
R2-D2: So I'm just short circuiting it by disguising myself as a can of whoop-ass and raiding the whole base. With my shock probe.
C-3PO: And I'm going in to help translate.
R2-D2: Yeah. The screams.
GM: We ended the last adventure with the party already split, and now you're starting this one by splitting it further?
C-3PO: So how do you intend to get into Jabba's Palace?
R2-D2: Walk up to the front door and knock.
{beat, R2 looks helplessly at the door}
R2-D2: Well, you knock.
